Do you need to undergo a CT Angio- Pulmonary Embolism? Read on to know all about it.
What is CT Angio- Pulmonary Embolism?
CT Angio- Pulmonary Embolism is a diagnostic test that makes use of contrast material to generate images of the arteries to detect a pulmonary embolism.
The CT Angio- Pulmonary Embolism procedure makes use of a CT (Computed Tomography) scanner to generate high-resolution images using an iodine-rich contrast chemical that is injected into the patient . The procedure is a minimally invasive one as it only requires one intravenous line, and is hence the preferred method of detecting pulmonary embolism.
How is CT Angio- Pulmonary Embolism performed?
CT Angio- Pulmonary Embolism is conducted in an exam room where the CT scanner is present.
- The patient lies on the examination table and the contrast material is injected.
- The table is then moved into the scanner, where rotating X-ray beams and X-ray detectors together detect the flow of contrast material through the body .
- A computer program translates this data into two-dimensional images that are presented on a computer in a separate control room.
- Following the exam, a bandage will be placed over the injection site.
Side effects/risks of CT Angio- Pulmonary Embolism
While CT Angio- Pulmonary Embolism is a safe procedure, possible risks and side effects include:
- Allergic reactions to the contrast material.
- Adverse effect of radiation on foetuses in pregnant women.
- Minor risk of radiation exposure during the scan.
Preparations before performing CT Angio- Pulmonary Embolism
The following preparations will ensure that CT Angio- Pulmonary Embolism happens safely.
- Patients are asked not to eat or drink for several hours before the procedure.
- All metal objects must be removed.
- Pregnant women should inform their physicians so that preparations can be made to reduce radiation levels.
Post-care after CT Angio- Pulmonary Embolism
No special post-care is required after CT Angio- Pulmonary Embolism. The results will be shared by the physician within a few days.
